    Dr Anil K Suresh

    SRM AP proudly congratulates Dr Anil K Suresh, Associate Professor, Department of Biological Sciences and his cohort of research scholars for their rare achievement of having their paper featured in the prestigious weekly news magazine Chemical and Engineering News (ACS-C&EN). The news article titled “This catalyst is a Golden Egg“, edited by Prachi Patel highlights the innovative research conducted by Dr Anil K Suresh and his team on developing a low-cost, sustainable catalyst by infusing eggshells with gold nanoparticles that can be reused and eventually recycled.

    The research paper titled Sustainable Bio-Engineering of Gold structured Wide-Area Supported Catalyst for Hand-Recyclable Ultra-Efficient Heterogeneous Catalysis (ACS Appl. Mater. Interfaces 2022, DOI: 10.1021/acsami.2c13564) highlights the team’s breakthrough advance in impregnating eggshells with gold nanoparticles to develop a cheap, and reusable ‘mega catalyst’. The research has used the robust “mega catalyst” to detoxify dye waste and run other organic reactions by dropping the eggshell catalyst into reaction solutions.

    Dr Suresh and colleagues dipped waste eggshells collected from restaurants in a suspension containing gold chloride for 6 hours. Consequently, the amino acids on the shells reduced the gold ions to form crystalline gold nanoparticles. Dr Suresh attested this method to be one of the simplest syntheses of a supported catalyst that was ever reported. He emphasised that he and his colleagues have also grafted catalytic silver and copper oxide on eggshells and are now working on methods to do this for platinum and palladium.

    SRM University-AP manifests pioneering advancement in innovative domains of research in the field of science and technology. The breakthrough research by Dr Anil K Suresh and his research team is of outstanding achievement and incredible addition to the institution’s laurels in the field of translational research.

  • Optimised copper nanoclusters for bio imaging applications July 15, 2022

    Research SRMAP

    Inspite of being a plentiful and inexpensive metal, the use of copper nanoclusters is limited in bio-medical research because of their toxicity and low stability due to its easily oxidizable nature. It also has a low quantum yield. The interdisciplinary publication of the researchers at SRM University-AP successfully addressed these constraints, resulting in strong fluorescence, superior colloidal stability, and non-toxicity of copper nanoclusters for bio imaging applications. The research was a collective work of Dr Manjunatha Thondamal from the Department of Biological Sciences, Dr Mahesh Kumar Ravva and Dr Sabyasachi Chakrabortty from the Department of Chemistry along with their PhD scholars; Mr Kumar Babu Busi, Ms Kotha Jyothi, Ms Sheik Haseena, Ms Shamili Bandaru and Ms Jyothi Priyanka Ghantasala.

    The article titled ‘“Engineering colloidally stable, highly fluorescent and nontoxic Cu nanoclusters via reaction parameter optimization” was featured in the prestigious Q1 journal RSC Advances (IF: 4.036), published by the ‘Royal Society of Chemistry’. They successfully prepared the protein stabilised copper nanoclusters inside the aqueous medium with exceptional optical properties. To the best of their knowledge, the reported colloidal stability and quantum yield of their as-synthesized Cu NCs are the highest reported in the literature, where the emission wavelength is in the red region. Also, optimised copper nanoclusters showed excellent biocompatibility towards solid cancer cell lines and C. elegans as in vitro and in vivo environments. Thus, these red colour luminescent copper nanoclusters were becoming a suitable fluorescent probe for deep tissue penetration, photodynamic, photothermal and diagnostic applications.

    Abstract of the Research

    Metal Nanoclusters (NCs) composed of the least number of atoms (few to tens) became very attractive for their emerging properties owing to their ultrasmall size. Preparing copper nanoclusters (Cu NCs) in an aqueous medium with high emission properties, strong colloidal stability, and low toxicity has been a long-standing challenge. Although they are earth-abundant and inexpensive, they are comparatively less explored due to their limitations such as ease of surface oxidation, poor colloidal stability, and high toxicity. To overcome these constraints, we established a facile synthetic route by optimizing the reaction parameters, especially altering the effective concentration of the reducing agent to influence their optical characteristics. The improvement of photoluminescence intensity and superior colloidal stability was modelled from a theoretical standpoint. Moreover, the as-synthesized Cu NCs showed a significant reduction of toxicity in both in vitro and in vivo models. The possibilities of using such Cu NCs as a diagnostic probe towards C. elegans were explored. Also, the extension of this approach towards improving the photoluminescence intensity of the Cu NCs on other ligand systems was demonstrated.

  • Interdisciplinary research and the integration of perspectives May 31, 2022

    Assistant professors Dr Sabyasachi Mukhopadhyay and Dr Imran Pancha from the Department of Physics and the Department of Biological Sciences, respectively, along with Ms Ashwini Nawade, a PhD student of the Department of Physics, have developed a method to integrate plant proteins in the solid-state electronic circuits and utilize the biological functionality to produce a thin film, cost-effective photodetector. Their paper entitled Electron Transport across Phycobiliproteins Films and its’ Optoelectronic Properties has been published in the ECS Journal of Solid State Science and Technology with an Impact Factor of 2.07. It is an interdisciplinary research project between the Department of Biotechnology and Physics.

    Explanation of the research

    Interdisciplinary research paperBiomolecules such as proteins, peptides being the most crucial life-forms, have an intimate relationship with various life activities for biological functions. The contemporary work with biomolecules mainly focuses on its evolving potential associated with nanoscale electronics where proteins and peptides are integrated as sensing materials. The researchers explored the optoelectronics functionality of combined proteins known as phycobiliproteins. They investigated electron transport behavior across the phycobiliproteins films under dark and white light illumination. The research affirms that the photochemical activity of the protein is more stable in a solid-state/ thin-film with tightly bonded water molecules than its presence in a buffer solution. Furthermore, the studies demonstrate that phycobiliproteins films modulate their electrical conductivity within their different conformation states. Researchers speculate that the electrical conductance variation could originate from the chemical alteration of cysteine-conjugated bilin chromophores to protein and the electrostatic environment around the chromophores.

    The research explores the photochemical properties and electrical transport efficiency of phycobiliproteins (PBPs) films. In addition, it investigates the optoelectronics functionality of PBPs films by studying electron transport behavior across the protein films under a dark state and white light illumination. The researchers proposed to develop a photodetector with the protein film in the future.

  • SRMAP Scholar wins best oral presentation award in International Conference March 4, 2022

    Mr Chandra S Bhatt, a PhD Scholar (CSIR-JRF) working under the guidance of Dr Anil K Suresh, Associate Professor, Department of Biological Sciences, has won the Best Oral Presentation Award at the International Conference on “Novel Materials and Technologies for Energy Applications,” organised by BITS Pilani-Hyderabad, on February 18-19, 2022. Prof Ashutosh Sharma, Former DST Secretary & Institute Chair Professor, IIT Kanpur, was the Chief Guest of the Conference.

    Abstract:

    Mr Bhatt’s project aims to develop the best out of waste, which is practically demonstrated by synthesising gold nanostructured eggshell-based supported catalyst. Besides this novel strategy, the megacatalyst is implemented in the real-time degradations of organic and sewage dyes that are harmful to the environment and hydrogenation of nitroarenes at gram-scale (precursors for various pharmaceutical ingredients). Our rationale, naturally created, stable, reusable, hand-removable, resilient catalyst developed from left-over food waste trounces the majority of the existing challenges while utilising nano-based catalysts for heterogeneous catalysis.

    With this innovation, Mr Bhatt aims to demonstrate pilot-scale (100-1000 litre) batch catalytic reactions for real-time textile sewage dye detoxification and gram scale hydrogenation of pharma-precursor for the production of acetaminophen, as a step of validation for immediate technology transfer and commercialisation for both environmental remediation and active pharmaceutical ingredients (API’s).

    About the Author:

    Mr Bhatt aims to continue his scientific career as a prominent scientist in the interdisciplinary area of nano-immunology for cancer theragnostics. Therefore, after the completion of his PhD, he wishes to advance his research career to contribute further to the realm of science upon postdoctoral training from a top-ranking institution abroad.

    “It is indeed a moment of pride for me to be awarded the Best Oral Presentation Award in an International Conference organised by BITS Pilani, Hyderabad, winning over 30 participants across the Nation. I express my heartfelt gratitude to my supervisor Dr Anil K Suresh, for his guidance and motivation me throughout the journey,” said Mr Bhatt.

    While expressing his joy, Dr Suresh emphatically said, “This was his first oral presentation in an International Conference, and he was conferred with the “Best Oral Presentation” Award. This recognition speaks for Chandra Sekhar’s dedication to his research. He has been working enthusiastically on this project, and I wish that the paper gets published in a high-impact journal which has already been communicated for Shekar’s bright scientific career.”

  • SRM University-AP publishes as the lead author among 21 co-authors from 13 countries February 14, 2022

    “Progress in Alternative Strategies to Combat Antimicrobial Resistance: Focus on Antibiotics” is a paper authored by Prof Jayaseelan Murugaiyan, Professor & Head, Department of Biological Sciences at SRM University-AP and his research scholar Ms Saranya Adukkadukkam, in Antibiotics Journal, having an impact factor of 4.639. It is a remarkable achievement that our university served as the first and the corresponding authors of this paper published in association with “Global AMR Insights Ambassadors Network”. A total of 21 co-authors from 13 countries (India, UK, France, The Netherlands, Switzerland, Italy, Spain, Ukraine, Lebanon, Egypt, Uganda, Bangladesh, and Nigeria) and six Indian universities (including SRM AP) participated in this work.

    Antimicrobial resistance (AMR) – the ability of microorganisms to survive antimicrobials – is a global healthcare concern. AMR contributes to 1.27 million deaths among the 4.95 million deaths associated with bacterial AMR. If no control measures are taken, it is estimated that by 2050, it will claim the lives of 300 million people. The rise of these “superbug bacteria’s” – means that trivial medical interventions will soon become once again high-risk since no efficient antimicrobial chemotherapy is available. It is, therefore, crucial to understand the current situation and identify alternatives to combat the emergence and spread of antimicrobial resistance. This paper comprehensively discusses the alternative approaches that can be effectively utilised to combat AMR and, at the same time, without inducing further resistance among the pathogens. The paper has great social implications in making society aware of the scenario and encouraging the researchers to focus on alternative strategies to combat AMR.

    Abstract of the paper: Antibiotic resistance, and, in a broader perspective, antimicrobial resistance (AMR), continues to evolve and spread beyond all boundaries. As a result, infectious diseases have become more challenging or even impossible to treat, leading to an increase in morbidity and mortality. Despite the failure of conventional, traditional antimicrobial therapy, in the past two decades, no novel class of antibiotics has been introduced. Consequently, several novel alternative strategies to combat these (multi-) drug-resistant infectious microorganisms have been identified. The purpose of this review is to gather and consider the strategies that are being applied or proposed as potential alternatives to traditional antibiotics. These strategies include combination therapy, techniques that target the enzymes or proteins responsible for antimicrobial resistance, resistant bacteria, drug delivery systems, physicochemical methods, and unconventional techniques, including the CRISPR-Cas system. These alternative strategies may have the potential to change the treatment of multi-drug-resistant pathogens in human clinical settings.

    Global AMR Insight Ambassador Network: AMR Insights, an international network-based organisation interacting with professionals around the globe: in Human and Veterinary Health, Agri-food and Environment, was set up in 2017 following an in-depth feasibility study towards a new information platform on AMR. It mainly focuses on informing, educating and connecting people with the aim to curb antimicrobial resistance. Prof Jayaseelan Murugaiyan and Ms Saranya Adukkadukkam are members of the Global AMR Insights Ambassador Network.

    Ms Saranya Adukkadukkam, the co-author from SRM AP says:

    The guidance of Prof Jayaseelan Murugaiyan is the pillar of my research. His support and passion for research always encourage me. He gives importance to translational research and motivates me to stand unique in the field. He shows me a path where I can serve the people through research. Foreseeing my future as a scientist, he guides me to more opportunities to collaborate with international scientists. I feel proud of my mentor Prof Jayaseelan Murugaiyan for letting me fly. Also, I thank SRM University-AP for providing generous fellowship, excellent research facilities and ambience to carry out the research.
